Archduke of Austria; as Ferdinand IV 1653–1654 Roman king (as the designated successor to his father, Emperor Ferdinand III)

Archduke Ferdinand was groomed from an early age by his father Emperor Ferdinand III as his successor on the throne. While still a youth he was crowned King of Bohemia (1646) and King of Hungary (1647), and at the age of nineteen elected Roman-German King. However, he never acceded as he died of smallpox when still a young man, prior to his father. He was succeeded as heir by his brother Leopold.
